I would rather not have 2 possible bindings to maintain. If there's
been no rush to upstream this til now, then it can wait longer.

There's obviously going to still need to be some sort of description
of the interface between cores, but this has parts that obviously
conflict with what's getting defined for system DT. The TCMs are the
most obvious. If you can remove (or hardcode in the driver) what
conflicts, then perhaps this can be upstreamed now.
